Australian Home Loan Rates Rise Following RBA Cash Rate Hikes

Australia’s cash rate reached 4.60% in September 2026 after the Reserve Bank delivered its fourth 0.25 percentage point increase of the year, taking rates to their highest level since late 2011. Major lenders then passed the increase through to variable home loan rates, lifting repayments for many borrowers.

For buyers in Melbourne’s western growth corridor, the biggest impact is reduced borrowing capacity. Higher mortgage rates mean households may qualify for smaller loans, forcing some purchasers to reconsider the size, type or location of the property they can afford.

This could shift more demand toward affordable houses, townhouses and units across the west. Buyers who previously targeted larger detached homes may increasingly focus on lower-priced suburbs or smaller properties to keep repayments manageable.

At the same time, weaker borrowing power can reduce overall competition. Sellers may face fewer buyers able to meet previous price expectations, creating more room for negotiation and potentially placing downward pressure on values in some parts of the market.

For existing homeowners, however, softer prices do not necessarily mean easier conditions. Higher variable rates directly increase mortgage repayments, adding to household cost pressures and making refinancing or upgrading more difficult.

Investors are also being squeezed by higher finance costs. Rental income may remain supportive in areas with strong tenant demand, but higher interest expenses can significantly reduce net returns, making careful cash-flow analysis more important.

The RBA has already noted that earlier rate increases have flowed through to higher mortgage payments and softer housing conditions.

Overall, Melbourne’s western growth corridor may become more attractive to buyers looking for value, but affordability will continue to depend heavily on finance costs. Lower purchase prices can create opportunities, yet buyers and investors still need to ensure repayments remain sustainable in a higher-rate environment.
